QUESTION
car A (mass 1100 kg) is stopped at a traffic light when it is rear-ended by car B (mass 1300 kg).
car A (mass 1100 kg) is stopped at a traffic light when it is rear-ended by car B (mass 1300 kg). Both cars then slide with locked wheels until the frictional force from the slick road (with a low µk of 0.10) stops them, at distances dA = 8.2 m and dB = 6.1 m.
